Modern purse seine work focuses on FADs (Fish Aggregating Devices). These floating rafts attract fish, making them easier to encircle. However, FADs also catch juvenile tuna and sharks. So, the work of fisheries scientists includes designing "non-entangling" FADs and teaching fishers how to release bycatch alive. 2.3 Hook and Line Gear – Selective & Sustainable This category includes handlines, longlines, and rod-and-reel.
